Frequently asked questions
What is the molar mass of C25H21NO4?
The molar mass of C25H21NO4 is 399.45 g/mol, calculated from standard atomic weights for 25 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom and 4 oxygen atoms. The monoisotopic mass is 399.1471 Da.
How many compounds have the formula C25H21NO4?
CompoundList lists 182 compounds with the molecular formula C25H21NO4, including Rel-(1R)-1-({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)-2,3-dihydro-1H-indene-1-carboxylic acid, N-(4-Methylbenzyl)-2-((2-oxo-4-phenyl-2H-chromen-7-yl)oxy)acetamide, 2-((2-Oxo-4-phenyl-2H-chromen-7-yl)oxy)-N-phenethylacetamide. Compounds that share a formula are isomers. They contain the same atoms arranged differently, so their properties, uses and prices can be very different.
What is the degree of unsaturation of C25H21NO4?
C25H21NO4 has a degree of unsaturation of 16. That is the total number of rings and pi bonds (a double bond counts as one, a triple bond as two) in any structure with this formula.
